Los Angeles: Singer-actress Selena Gomez has returned home after her month's long treatment in a mental health treatment center.

Selena Gomez is back home and "focused on her physical and mental well-being" after seeking mental treatment following some health scares.

"She's focused on her physical and mental well-being and is conscious of the things she needs to do to stay healthy," the source continued. "She has a routine that involves working out, eating healthy and therapy sessions.

She is surrounding herself with her best girlfriends and positive influences in her life. She's happy to be back home and seeing friends again

Gomez was photographed for the first time in more than two months during a hike in Malibu, California, with friends.

A source close to the "The back to you" hit maker told the publication that Gomez is feeling better after her treatment.

"Selena looks amazing. Since finishing her treatment, she is surrounding herself with friends. She seems very happy," the source added.

The actress was hospitalized twice in October, both times for a low white blood cell count, which can be a side effect for kidney transplant patients.

During her second visit, Gomez suffered a panic attack and subsequently headed to a treatment centre on the East Coast.

Earlier this week, she was spotted out in Hollywood and was also all smiles on a trip to snowy Big Bear, California with her pals, which included fellow Wizards of Waverly Place alum Bailee Madison.
